Review Meta AnalysisEffect of Immediate Administration of Antibiotics in Patients With Sepsis in Tertiary Care: A Systematic Review and Meta-analysis.
The goal of this review was to synthesize existing evidence regarding outcomes (mortality) for patients who present to the emergency department, are administered antibiotics immediately (within 1 hour) or later (>1 hour), and are diagnosed with sepsis. ⋯ Immediate antibiotic administration (<1 hour) seemed to reduce patient mortality. There was some minor negative asymmetry suggesting that the evidence may be biased toward the direction of effect. Nevertheless, this study provides strong evidence for early, comprehensive, sepsis management in the emergency department.

Predictive Modeling of Response to Pregabalin for the Treatment of Neuropathic Pain Using 6-Week Observational Data: A Spectrum of Modern Analytics Applications.
This post hoc analysis used 11 predictive models of data from a large observational study in Germany to evaluate potential predictors of achieving at least 50% pain reduction by week 6 after treatment initiation (50% pain response) with pregabalin (150-600 mg/d) in patients with neuropathic pain (NeP). ⋯ The finding that pain changes by week 1 or weeks 1 and 3 are the best predictors of pregabalin response at 6 weeks suggests that adhering to a pregabalin medication regimen is important for an optimal end-of-treatment outcome. Regarding baseline predictors alone, considerable published evidence supports the importance of high baseline pain score and presence of depression as factors that can affect treatment response. Future research would be required to elucidate why using pregabalin as a monotherapy also had more than a 10% variable importance as a potential predictor.

Randomized Controlled Trial Comparative StudyEfficacy of Methylprednisolone Acetate Versus Triamcinolone Acetonide Intra-articular Knee Injection in Patients With Chronic Inflammatory Arthritis: A 24-Week Randomized Controlled Trial.
Triamcinolone hexacetonide (TH), triamcinolone acetonide (TA), and methylprednisolone acetate (MPA) are commonly used intra-articular steroid preparations. Studies suggest that intra-articular TH is more efficacious than MPA and TA in chronic inflammatory arthritis. However, it is unclear which of the latter two preparations has better efficacy. Thus, we compared intra-articular knee injections of MPA and TA in patients with chronic inflammatory arthritis. ⋯ No significant differences were found in efficacy between intra-articular knee injections with MPA and TA in these patients with chronic inflammatory arthritis. However, results need to be extrapolated cautiously because of the small sample size. Three-quarters of the patients remained relapse free at 24 weeks.

Randomized Controlled TrialDexmedetomidine Added to Local Anesthetic Mixture of Lidocaine and Ropivacaine Enhances Onset and Prolongs Duration of a Popliteal Approach to Sciatic Nerve Blockade.
A literature review of multiple clinical studies on mixing additives to improve pharmacologic limitation of local anesthetics during peripheral nerve blockade revealed inconsistency in success rates and various adverse effects. Animal research on dexmedetomidine as an adjuvant on the other hand has promising results, with evidence of minimum unwanted results. This randomized, double-blinded, contrastable observational study examined the efficacy of adding dexmedetomidine to a mixture of lidocaine plus ropivacaine during popliteal sciatic nerve blockade (PSNB). ⋯ Perineural dexmedetomidine added to lidocaine and ropivacaine enhanced efficacy of popliteal approach to sciatic nerve blockade with faster onset and longer duration.

Review Comparative StudyIndirect Treatment Comparisons of Ibrutinib Versus Physician's Choice and Idelalisib Plus Ofatumumab in Patients With Previously Treated Chronic Lymphocytic Leukemia.
Treatment options for patients with relapsed or refractory chronic lymphocytic leukemia (R/R CLL) are limited. Until recently, few effective treatment options existed, and even with the advent of new agents, studies evaluating comparative efficacy are scarce. In the Ibrutinib Versus Ofatumumab in Patients With Relapsed or Refractory Chronic Lymphocytic Leukemia (RESONATE) Phase III study, ibrutinib, an oral, once-a-day, first-in-class covalent Bruton tyrosine kinase inhibitor, improved progression-free survival (PFS) and overall survival (OS) compared with ofatumumab (PFS hazard ratio [HR] = 0.106 and OS HR = 0.369 [adjusted for crossover] at a median of 16 months' follow-up). We sought to establish the relative efficacy of ibrutinib versus other treatment options for patients with R/R CLL using indirect comparison methods. ⋯ In a randomized Phase III study, ibrutinib significantly improved ORR, PFS, and OS in patients with R/R CLL versus ofatumumab. In ITC models that used ofatumumab as the common comparator, ibrutinib appears to have higher ORR and longer PFS and OS versus both idelalisib plus ofatumumab and physician's choice. In the absence of head-to-head studies and taking into consideration inherent limitations of ITCs, these models provide useful estimates of comparative efficacy.
